Abstract

The invention provides a constant power ballasting component, comprising: a magnetic core; a main coil arranged in the magnetic core, wherein the main coil at least includes a first tap, a second tap, a third tap and a fourth tap, wherein a coil of first number of turns is arranged between the first tap and the third tap, a coil of second number of turns is arranged between the first tap and the second tap, and a coil of third number of turns is arranged between the first tap and the fourth tap; a control unit that detects an input voltage and switches on one of the second, third and fourth taps and the first tap selectively according to the input voltage. The constant power ballasting component allows the corresponding number of turns to be adjusted and the tapping to be performed during winding of a choke coil according to voltage fluctuation, so that a lamp is kept operating substantially under the rated power to save energy.

Description

technical field [0001] The invention relates to a ballast assembly, in particular to a constant power ballast assembly suitable for high-intensity gas discharge lamps. Background technique [0002] At present, in areas with large voltage fluctuations, CWA or CWI flux leakage constant power inductive ballasts with magnetic shunts are generally used in the market to maintain the rated power of the lamp to ensure the lighting quality and prolong the life of lighting appliances. [0003] However, the CWA or CWI flux leakage ballast in the prior art has the disadvantages of high manufacturing cost, low efficiency, large power consumption, and large volume. Contents of the invention [0004] Aiming at the actual application needs in the industry, the present invention proposes a brand new constant power ballast assembly. [0005] Specifically, the present invention proposes a constant power ballast assembly, including: [0006] magnetic core; [0007] The main coil is arrange...
